Description
Technical field
The present invention relates to a kind of agitating device, especially a kind of industrial liquid agitating device being applied to liquid agitation, belong to industrial application.
Background technology
Agitating device generally comprises motor, and the swingle that motor connects, also has the stirrer paddle composition being arranged on swingle, agitating device effect is to make liquid, the mixed uniformly equipment of gas medium forced convection, most of agitating devices of current industrial utilization are all that structure is single, and during the stirring bigger liquid medium of density, mixing effect is bad, and the service life of agitating device parts is shorter.
The purpose of stirring: Liquid-liquid mixing, gas-liquid mixing and solid-liquid mixing.The influence factor of stirring has several as follows:
1) power of agitator distribution between overall flow and turbulence pulsation is had impact by the type of agitator, size and rotating speed.
2) the stirring viscosity of different medium viscosity refers to the resistance capabilities that fluid convection is dynamic, is called dynamic viscosity.Fluid, when flowing, is divided into laminar flow, transition flow, three kinds of states of turbulent flow, and determines the principal element of these three state and the viscosity of fluid.
3) internals stirred particularly impeller, guide shell, baffle plate etc. are also the key factors of impact stirring.
Other
The motion of liquid in agitator tank, is divided into overall flow and turbulence pulsation from yardstick.The flow of overall flow is called circulating load, adds big cycle volume and is conducive to improving the degree of mixing well (see mixability) of micromixing.The speed when intensity of turbulence pulsation leaves agitator with fluid is relevant, strengthens turbulence pulsation and is conducive to reducing and separates yardstick and segregation intensity.Both flowings are had different requirements by different processes.Drop, bubble dispersion, it is necessary to strong turbulence pulsation；The even suspension of solid particle, depends on overall flow.Energy distribution on both flows during stirring, is stirring for the major issue in device design.
When stirring mixture, stirring operation is had a significant impact by biphase density contrast, viscosity and interfacial tension.Density contrast and interfacial tension are more little, and system more easily reaches stable dispersion；Viscosity is more big more is unfavorable for being formed good circulating and enough turbulence pulsations, and consumes bigger power of agitator.
In agitator tank, the motion of fluid is complicated single-phase flow or multiphase flow.The stirring of non-Newtonian fluid, has some special rules in flow regime and power consumption.The measurement of fluid flow parameters in agitator tank, power of agitator it is expected that and the amplification method etc. of agitating device, be all stirring for the important topic in theoretical research and engineer applied.
Viscosity refers to the resistance capabilities that fluid convection is dynamic, and it is defined as: when liquid flows with the speed of 1cm/s, and in every 1cm2 plane, the size of required shear stress, is called dynamic viscosity, in units of Pa s.Viscosity is an attribute of fluid.When fluid flows in pipeline, there are laminar flow, transition flow, three kinds of states of turbulent flow, mixing plant there is also these three flow regime equally, and one of major parameter determining these states is exactly the viscosity of fluid.In whipping process, it is considered that viscosity is low viscosity fluid less than 5Pa/s, for instance water, Oleum Ricini, maltose, fruit jam, Mel, lubricating oil heavy oil, low slimy milk liquid etc.；5-50Pa/s's is medium viscosity fluids, for instance ink, toothpaste etc.；50-500Pa/s's is high viscosity fluid, for instance chewing gum, plastisol, solid fuel etc.；More than 500Pa/s be extra-high rheid such as: rubber composition, plastic melt, organosilicon etc..For low-viscosity media, fluid circulation around just can be driven with the high-revolving agitator of minor diameter, and at a distance.And the fluid of high viscosity medium is quite different, direct agitator is needed to promote.Suitable in low viscous and the impeller of rheid have paddle, open turbine formula, push type, long slender lobule propeller type, orbital, Bu Lumajinshi, sheet frame paddle, SANYE swept-back, MIG formula etc..Impeller suitable in highly viscous and extra-high rheid has helical-ribbon type impeller, screw, anchor formula, frame, propeller type etc..Some fluid viscosities carry out with reaction and change, it is necessary to the impeller that can be suitable for width viscosity field, such as general energy formula impeller etc..
It is the patent of invention in May 15 in 2013 if publication number is CN103100345A publication date, this agitator includes the first blade and one end and connects the shaft of the device clutch end that reduces by half, the middle part of the first blade and the other end of shaft are fixedly connected, the sleeve also include the second blade, being socketed on shaft to slide along shaft and the motor that is fixed on shaft, the outfan of motor is connected to the expansion link for push-and-pull sleeve, one end of second blade is hinged with the end points of the first blade, is hinged with adjusting rod between the other end and the sleeve of the second blade；This patent can regulate mixing position so that liquid agitation is uniform, but its blade is shorter, does not reach good stirring, and secondly, the second blade quantity is also more, and the resistance of stirring strengthens, and adds cost.Disclosure CN104014268, date of publication is in JIUYUE, 2014 patent of 3 days, propose a kind of agitator, including the blade being connected with motor by swingle, the lower end of described swingle and a supporting seat abut against, supporting seat has base, base upper end is provided with the support bar being vertically to horizontal plane, the external wall of upper portion of support bar is provided with screw thread, screw thread is set with the nut adjusting described support bar height, agitator is when rotated, non-loosening, without waving, and blade such as does not come off at the advantage, but blade design is too single, during agitated liquid, mixing power lacks, this patent is when pursuing lightweight conveniently moving, the effect making stirring is greatly reduced.
Therefore, for existing disclosed technology and practical application, this patent is directed to one and overcomes existing structure design mixing effect undesirable, and mixing time is long, the new solution that energy consumption is big.
